I already overheard my brother say that he may not vote for Likud because of this, and in this report, it's told:

Demonstrators in Israel's South called on Netanyahu not to agree to a ceasefire, but to restore deterrence and security. A Channel 2 political analyst noted that the demonstrators are largely Likud voters and said Netanyahu will have a problem with these voters if he agrees to a ceasefire at present.

Oh yes, there's some truth to that. We'll see how things turn out in coming weeks and month, but for now, he may have jeopardized his party's electoral chances by taking such an atrocious risk.

On the TV news, I heard that Ehud Barak, Dan Meridor and Benny Begin pushed for this. But even so, Netanyahu's own weakness here could very well end up costing the Likud very badly.
